Background and Objective: Considering the relatively wide application of ceftriaxone in pediatric infectious diseases and its side effects, this study was done to determine gallblader sonographic abnormality following ceftriaxone treatment in children.

Materials and Methods: This descriptive cross- sectional study was carried out on 60 patients age 1 month up to 12 years in Besat hospital, Hamadan, Iran during 2007. The sonographic abnormal finding of gallbladder before ceftriaxone therapy and 5 days after therapy were recorded. In case of any abnormality in gallblader sonography was repeated twice a week in the first two weeks and afterward once a week up to disappearance of abnormalities.

Results: Gallblader sonographic abnormality were observed in 10 cases (16.5%). Out of them, 8 and 2 patients had bile stone and bile sludge, respectivley. The patients did not show any clinical manifestations. There was no relation between age and sex with abnormal findings. Gallblader abnormality completely were disappeared in the worst cases by sixteen days.

Conclusion: This study showed that the incidence of either gallstone or biliary sludge after treatment with ceftriaxone was 16.5% which is relatively similar to other studies.

Background and Objective: Cardiovascular diseases are the most frequent cause of death among hemodialysis patients. Left ventricular hypertrophy and systolic dysfunction are potent predictors of cardiovascular morbidity and mortality in hemodialysis patients. Cardiac troponin T and I are the indices of myocardial cell damage. This study was done to determine the relationship between serum cardiac troponin T and I with left ventricular hypertrophy and systolic dysfunction in hemodialysis patients. Method: In this case-control study, 56 hemodialysis patients were divided into two groups according to echocardiographic findings. The first group included 35 patients with left ventricular hypertrophy as case group and 21 patients without left ventricular hypertrophy as controls. Serum level of cardiac troponin T and I were measured using electro chemiluminscence immune assay. Results: Serum level of cardiac troponin T and I was significantly higher in patients with left ventricular hypertrophy (0.99±0.12 ng/ml and 0.17±0.09 ng/ml, respectively) in comparison with controls (0.37±0.05 ng/ml and 0.13±0.09 ng/ml, respectively) (P<0.05). There was no correlation between serum cardiac troponin T and I level with left ventricular systolic dysfunction. Conclusion: Cardiac troponin I and T do not have any value for the diagnosis of left ventricular systolic dysfunction in hemodialysis patients.

Background and Objective: Systemic lupus erythatous (SLE) is an autoimmune disease with clinical symptoms. Anti neutrophil cytoplasmic antibody (ANCA) is common in vasculitis which is reported in SLE. This study was done to determine the frequency of ANCA in patient with SLE and its association with disease activity.
Methods: This descriotive study was conducted on 80 patients with SLE whom referred to rheumatology clinic in Gorgan, northern Iran during 2012-15. The patients disorder diagnosed based on the ACR Criteria. According to the disease activity the patients divided to active group and inactive group. Demographic data was completed with questionnaire and blood sample collected in order to evaluate of for serum ANCA by using ELISA method.
Results: The average age was 37.5±12.4 year. Seven (8.5%) patients were males. 91.5% of patients was females. 27 patients (33%) had active lupus and 53 (57%) had inactive lupus. Only one patient has been reported as positive for ANCA. The patient was a 45 years woman with history of 10 years of lupus nephritis with active disease.
Conclusion: There was no relationship between ANCA and disease activity. The main reason for this finding can be a few numbers of positive cases in this study.
